Aim of the Project The Fifth Generation Computer Systems (FGCS) project is a Japanese Na- tional project aimed at new computer technology for knowledge information processing. This project proposed that "logical inference using knowledgebases" is the ker- nel function of future knowledge information processing, and adopted logic pro- gramming as the kernel programming language of the FGCS. The project aimed at creating a new computer technology combining knowledge processing with parallel processing using logic programming. FGCS Prototype System To evaluate the various element computer technologies to be developed in the project, an FGCS prototype system was to be built by the end of the project. Since 1982, the Institute for New Generation Computer Technology, ICOT, has been conducting research and development on new theories and technologies for the FGCS project. Now, the FGCS prototype system has been completed, integrating the major research and development achievements of the past 10 years, and is ready to challenge new and larger knowledge processing applications. - 1 -
